EFFICIENCY OF MONETARY POLICY IMPLEMENTATION AS A BASIS FOR CENTRAL BANK STABILISATION POLICY UNDER MARTIAL LAW (UKRAINIAN AND ISRAELI PRACTICES)

The purpose of the paper is to summarise and present the anti-crisis practices of a central bank during martial law in the country, based on the experience of the National Bank of Ukraine and the Bank of Israel. The research methodology is based on an analysis of reports, guidelines, statistical data, scientific articles, legislation bases, and other relevant materials. One of the methodological aspects of this study is a comparison of the knowledge acquired about the regulations implemented by the two central banks after the introduction of martial law in the countries. The objective is to identify potential lessons learned for the banking regulations of Ukraine and the State of Israel. The results of the study show that the practical implementation of stabilisation measures by central banks is crucial for achieving financial stability of the state both during and after wartime, as well as the ability to predict possible deepening of crises and minimise their consequences. The tools and methods used by these central banks differ. In particular, the NBU's main monetary policy instrument was foreign exchange interventions, while the BoI actively used the key policy rate. The proper formation of international currency reserves and the possibility of using them during a war-related crisis is critical for both countries. This fact confirms that crisis management has different types of scenarios. Each anti-crisis scenario is unique. This paper highlights the practical need for interaction between monetary and macroprudential policies of the central bank in wartime. It demonstrates various combinations of methods and instruments of the central bank's monetary policy. This study also shows the interdependence of the economies of these two countries. Practical implementation. This analysis provides insight into the anti-crisis activities of central banks during unpredictable periods in a country's life, namely, during martial law. At the present stage, banking systems do not often face the challenges of war. Therefore, studying each case is important for improving theoretical knowledge and deepening practical research. Value / Originality. The author of the study collected the experience and practices of stabilisation activities of the central banks of Ukraine and Israel during the war.

The Real Equilibrium Exchange Rate of the Czech Koruna – the BEER Approach

The aim of this paper is to develop a model of the real equilibrium CZK/EUR exchange rate with all relevant explanatory variables. Emphasis will be placed on examining the longest possible time horizon, with a period of real convergence, but also economic stagnation. The model is based on the theoretical BEER approach using a cointegration or error correction model that distinguishes between short-term and long-term relationships. The results show that the Czech koruna strengthens when the productivity differential, terms of trade differential or gross fixed capital formation increase, while the koruna weakens when the VIX index representing global risk aversion increases. For the real interest rate differential, the hypothesis that the koruna strengthens in the short run during the improvement but weakens in the long run probably due to the country's risk premium, was confirmed. Moreover, it turned out that the start of the European Central Bank's quantitative easing led to strengthening of the Czech koruna, while the start of the CNB's foreign exchange interventions in 2013 led to weakening of the Czech koruna.

Capital controls in China: A necessity for macroeconomic stability

This paper investigates the crucial role of capital controls in maintaining macroeconomic stability in China. We develop an open macroeconomic model integrating capital controls within a managed floating exchange rate system. Our model shows that capital controls enhance the effectiveness of foreign exchange interventions by restricting capital outflows and providing a broader array of policy options, though they may also create discrepancies between domestic and foreign asset holdings. Simulations using quarterly time-series data reveal that capital controls are essential for the success of both sterilized and non-sterilized interventions. These results indicate that the combined use of capital controls and foreign exchange interventions can reduce macroeconomic volatility in China. Moreover, our analysis of fixed versus floating exchange rate regimes suggests that an inappropriate regime choice can increase volatility in capital flows. Therefore, China should adopt a balanced financial approach within its managed floating system to stabilize the macroeconomy.

Blowing against the Wind? a narrative approach to central Bank foreign exchange intervention

Most countries in the world use foreign exchange intervention, but measuring the success of the policy is difficult. By using a narrative approach, I identify interventions when the central bank manages to influence the exchange rate based on pure luck. I separate them from interventions when the central bank actually impacted the exchange rate. Because intervention records are daily aggregates, an intervention might appear to have changed the direction of the exchange rate, when it is more likely to have been caused by market news. This analysis allows to have a better understanding of how successful central bank operations really are. I use new daily data on Bank of England interventions in the 1980 s and 1990 s. Some studies find that interventions work in up to 80 % of cases. Yet, by accounting for intraday market moving news, I find in adverse conditions, the Bank of England managed to influence the exchange rate only in 8 % of cases. I use natural language processing to confirm the validity of the narrative approach. Using lasso and a VAR analysis, I investigate what makes the Bank of England intervene. I find that only movement on the Deutschmark and not US dollar exchange rate made the Bank intervene. Also, I find that interest rate hikes were mostly a tool for currency management and accompanied by large reserve sales.

Impact of exchange rate on economic growth in Nigeria

This study examined the effect of exchange rate dynamics on economic growth in Nigeria from 1985 to 2021. The study utilized secondary data sources from the World Development Indicators (WDI) and the Central Bank of Nigeria (CBN) Statistical Bulletin. It employed real gross domestic product as a measure of economic growth. In addition to the official exchange rate as a proxy for exchange rate dynamics, the study integrated other domestic factors that can affect economic growth, such as trade openness and external reserves. The econometric techniques employed in the study were unit root tests, cointegration, and autoregressive distributed lag (ARDL)/bound techniques. Following the outcome of the bound test, it was reported that a long-run relationship exists between economic growth, exchange rate, trade openness, and external reserves. The long-run ARDL results reveal that the exchange rate had a positive and statistically significant effect on real GDP in Nigeria, with a unit increase in the exchange rate raising the real GDP by 0.3986 units in the long run; trade openness had a positive and not statistically significant impact on real GDP in Nigeria, suggesting that a unit increase in trade openness increases real GDP by 0.0025 units in the long run; and external reserves had a positive and statistically significant impact on real GDP in Nigeria, indicating that a unit increase in external reserves increases real GDP by 0.4007 units in the long run. Based on the results, the study recommends that the government should develop policies that stabilize the exchange rate. This could involve enhancing foreign exchange reserves management, improving the transparency and predictability of foreign exchange interventions, and possibly considering a more flexible exchange rate regime that can adapt to external shocks while maintaining stability. Policies should focus on gradually opening up the economy to international trade through strategic trade agreements that protect key domestic industries while promoting sectors where Nigeria has a competitive advantage. This approach will help mitigate any negative short-term impacts while capitalizing on long-term benefits. Keywords: Exchange Rate, Trade Openness, External Reserves and Real Gross Domestic Product.

UKRAINE’S MONETARY POLICY UNDER MARTIAL LAW

The relevance of the research is due to the change in the monetary policy regime of the National Bank of Ukraine (NBU), which consists in the transition from inflation targeting with a floating exchange rate to a fixed exchange rate as the nominal anchor of monetary policy under martial law. Such a plan to change the monetary policy regime was carefully calculated and outlined in the NBU's Monetary Policy Guidelines for the Duration of Martial Law. The timeliness and effectiveness of the NBU's monetary policy decisions enabled it to mitigate the impact of the military shock on the macro-financial stability of the national economy. The purpose of the article is to consider the theoretical and practical aspects of the NBU's monetary policy under martial law. Methodology. The study uses a systematic method of cognition to determine the sequence of application of monetary policy instruments to smooth out monetary shocks of the wartime period; an abstract-logical method to understand the future monetary policy strategy based on the abandonment of the fixed exchange rate regime and a gradual return to inflation targeting; and a statistical method to analyse the dynamics of monetary indicators of the national economy. Results. The paper presents the main principles of the NBU's monetary policy under martial law. The first shock from the war led to changes in the conduct of monetary policy and a shift to unconventional instruments of its regulation. The gradual adaptation of the economy to the new conditions determined the NBU's further steps to ease monetary policy and move to greater exchange rate flexibility. Practical implications. The practical significance of the research results is to assess the conditions for the transition from the key policy rate-based inflation targeting regime as the main monetary policy instrument to the use of foreign exchange interventions as the main operation in the foreign exchange market under martial law. Value / Originality. The originality of the article is due to the need to identify the prerequisites for the transition to a new monetary policy strategy in a wartime economy. Conclusions. The NBU's timely response to the negative phenomena associated with deteriorating inflation expectations, multiple exchange rates and pressure on international reserves helped prevent the development of a currency and financial crisis in Ukraine. Despite the active hostilities, the NBU is trying to find options that will allow it to conduct an effective monetary policy in the face of a full-scale invasion and unprecedented internal and external shocks. Internationally, Ukraine has exceeded expectations and the NBU has shown a high degree of responsibility, professionalism and creativity in the conduct of monetary policy. Increased confidence in the central bank is a valuable resource in times of martial law.

Stochastic intervention control of mean-field jump system with noisy observation via L-derivatives with application to finance

In this paper, we investigate stochastic optimal intervention control of mean-field nonlinear random Poisson-jump-system with related noisy process. We derive the necessary conditions of optimality for partially observed optimal intervention control problems of mean-field type. The coefficients depend on the state of the solution process as well as of its probability distribution and the control variable. The proof of our main result is obtained by applying L-derivatives in the sense of Lions. In our control model, there are two models of jumps for the state process, the inaccessible ones which come from the random Poission process and the predictable ones which come from the intervention control. Finally, we apply our result to study conditional mean-variance portfolio selection problem with interventions, where the foreign exchange interventions are intended to contain excessive fluctuations in foreign exchange rates and to stabilize them.

Some implications of behavioral finance for international monetary analysis

This paper discusses some of the important insights from behavioral finance for international monetary and financial analysis. A broad approach to behavioral finance is advocated which includes analysis of the effects of uncertainty, perverse incentives, and complexity economics as well as the cognitive biases focused on in the initial contributions to behavioral finance. It offers reasons why capital mobility is often not perfect and expectations are sometimes not rational. Correctly interpreted it is not a wholesale attack on efficient market theory but rather argues that markets can behave differently at different times, being efficient sometimes and subject to destabilize or insufficiently stabilizing speculation at others and focuses on the conditions that make different types of behavior more likely. It helps provide insights into issues such as currency crisis, the effects of official intervention in foreign exchange markets, the international monetary trilemma, capital flow surges and reversals, the discipline effects of fixed exchange rates and international financial markets and why uncovered interest rate parity often does not hold.

Foreign Exchange Intervention: A Data Set of Official Data and Estimates

AbstractA better understanding of foreign exchange intervention (FXI) is often hindered by the lack of data. This paper provides a new data set of FXI covering a large number of countries since 2000 at monthly and quarterly frequencies. It includes published official data for about 40 countries as well as carefully constructed estimates for 122 countries. Estimates account for a wide range of central bank operations, including both spot and derivative transactions. These estimates improve upon traditional proxies based on changes in reserves, by adjusting for valuation changes, income flows, and changes in other foreign‐currency balance sheet positions (both vis‐à‐vis residents and nonresidents)—the first estimates to do the latter to our knowledge—thus providing a more accurate measure of operations that change the central bank's foreign currency position. The data set also provides a classification of FXI operations into sterilized or not sterilized, a key dimension for economic analysis. Finally, the paper discusses the merits of the new estimates relative to traditional proxies, and presents stylized facts.

The effectiveness of macroprudential policies in managing extreme capital flow episodes

AbstractAgainst the backdrop of a proliferation of policy tools in recent years, there is ongoing policy uncertainty surrounding the suitability of capital flow management in mitigating systemic risk and financial disruptions. We study the effectiveness of macroprudential policies in managing extreme capital flow episodes (surges, stops, flight, and retrenchment), comparing them to capital controls and foreign exchange interventions. Using propensity score matching, based on a panel of 54 countries spanning 1990Q1 to 2020Q3, we find that macroprudential policy can reduce the likelihood of extreme capital flow episodes at least as effectively as capital controls or foreign exchange interventions. Their relative effectiveness, however, varies considerably across type of instrument, proliferation of tools, country income‐development level, and type of extreme capital flow episode.

АНАЛІЗ ЕФЕКТИВНОСТІ ВИКОРИСТАННЯ ІНСТРУМЕНТІВ ВАЛЮТНОЇ ПОЛІТИКИ В УКРАЇНІ В ПЕРІОДИ КРИЗ 2008–2009 ТА 2019–2020 РОКІВ

The article is devoted to the analysis, comparison and evaluation of the effectiveness of the foreign exchange policy instruments used during the crises of 2008-2009 and 2019-2020 in Ukraine. The main types of instruments of foreign exchange regulation and the priority areas of their application were defined. The authors took under consideration the key features of the construction of the socioeconomic model of Ukraine, the geopolitical situation, and the imposition of cyclical fluctuations during the considered periods. In the course of the study, the exchange rate fluctuations of the national currency against the US dollar were monitored to determine dynamics of the devaluation and revaluation processes within the given time frames. In order to detail the regulatory foreign exchange policy, a separate analysis of the use of NBU tools within the current and long-term strategy was carried out, the differences were identified and the consequences were outlined. The conducted research showed that during both crises the discount policy, namely the change in the discount rate, was most actively used. But the changes were somewhat divergent: more aggressive liberal measures taken to reduce the discount rate during the 2019-2020 crisis appeared to be more effective compared to the crisis of 2008-2009. This is evidenced by data on changes in GDP PPP, indicating the best positive dynamics when exiting the recession during the pandemic. However, in both cases, significant devaluation was observed. In order to determine the causes and consequences of the depreciation of the national currency in relation to the US dollar and other currencies, an analysis of the balance of payments accounts was carried out by individual articles. This made it possible to indicate significant differences in the nature of the origin of these crises. The instruments of motto policy were also used with varying degrees of activity and in the opposite direction. Foreign exchange interventions in 2008-2009, in contrast to the period of 2019-2020, were used very limitedly due to the rather rapid depletion of gold and foreign exchange reserves. Foreign exchange restrictions were strengthened in 2008-2009, and liberalized in 2019-2020. As a result, it allowed to revive investment flows and improve the business climate in the country. It is also noted that against the background of general devaluation during both crises, a period of revaluation of the national currency was also observed in 2019. The analysis showed that in that case it was rather a negative phenomenon, which led to significant losses in the revenue part of the budget due to a decrease in revenues from customs payments, resulted from the inconsistent actions of the NBU and relevant ministries. Other elements of foreign exchange policy were almost not used: the degree of currency convertibility and the exchange rate regime did not change (with the exception of a short period of introduction of the exchange rate band). The same can be said about the instruments of the long-term foreign exchange policy: the order of international settlements was slightly adjusted, but not significantly; the regime of exchange rates and parities remained unchanged; the use of gold and reserve currencies was combined with the diversification of foreign exchange reserves and was mainly related to foreign exchange interventions and the fulfillment of external debt obligations. The conducted analysis allowed to identify the main directions of the foreign exchange policy of Ukraine regarding the stabilization of the economy and the achievement of sustainable economic growth. To solve this problem, it is advisable to gradually introduce foreign exchange liberalization, introduce new reforms and state projects that might improve the investment climate. It is also appropriate to de-dollarize the debts of enterprises through incentives for lending in the national currency. In the long term, it is appropriate to strengthen financial and capital markets to ensure the stability of economic growth.

Inflation targeting, exchange rate and output gap in Central and Eastern European countries

This paper aims at empirical assessment of monetary policy relationships in Central and Eastern European countries (Czechia, Hungary, Poland, Romania), which practise the monetary regime of inflation targeting. Using quarterly data for the period of 2004-2019, the authors examined the relationship between the output gap, nominal and real exchange rate misalignment, consumer price inflation and the central bank policy rate, using the panel vector autoregression (PVAR) model. According to estimates, the central banks of the CEE-4 countries react with an increase of their policy rate to the output gap and inflation, as implied by the Taylor rule. At the same time, a monetary reaction to nominal (real) exchange rate misalignment is lost in the estimates for the post-crisis period of 2010-2019. An increase of the central bank rates does not seem to have unfavourable output effects, while the nominal exchange rate is likely to depreciate with three to five quarter lags. However, there is evidence of the price puzzle when monetary tightening is followed by a counterintuitive increase in the inflation rate. In full accordance with the New Keynesian framework, inflation depends on the output gap, while being expansionary in the real sector. Evidence of the exchange rate pass-through (ERPT) to inflation is mixed. This article provides insights into the average monetary policy reaction function and its macroeconomic effects in the CEE-4 countries, with the value added in that following the Taylor rule does not guarantee effectiveness in tackling inflation in the presence of the price puzzle. Based on the estimated exchange rate effects on the output gap and inflation, deliberate currency appreciation resulting from the central bank foreign exchange interventions and/or fiscal austerity measures can be helpful for such a disinflation that minimises output losses.

Foreign Exchange Pressure and Foreign Exchange Intervention in Nigeria: A Review of Literature

This paper conducts a comprehensive examination of the concepts of foreign exchange pressure and foreign exchange intervention within the Nigerian foreign exchange market. It delves into the theoretical foundations and empirical evidence underpinning these crucial elements of economic policy in Nigeria. To begin, the paper elucidates the various factors driving foreign exchange pressure in the Nigerian context, encompassing trade imbalances, external shocks, and economic fluctuations, which exert significant pressure on the exchange rate and foreign exchange reserves, necessitating effective strategies for policymakers and market participants. Furthermore, the paper sheds light on the theoretical frameworks and models that form the basis of foreign exchange intervention, emphasizing the substantial impact of central bank and government interventions on maintaining foreign exchange market stability, averting abrupt currency devaluations, and upholding macroeconomic equilibrium. Additionally, the paper reviews empirical literature, offering valuable insights into the practical implications of foreign exchange pressure and intervention in Nigeria, showcasing the Nigerian central bank's use of measures like capital controls, foreign exchange auctions, and exchange rate pegs. The effective management of foreign exchange pressure in Nigeria plays a pivotal role in ensuring economic stability, bolstering international trade, and fostering sustainable economic growth within the nation.

Does the Interest Parity Puzzle Hold for Central and Eastern European Economies?

AbstractThis paper examines the uncovered interest parity puzzle in Central and Eastern European countries. Apart from investigating baseline UIP regressions, we check for structural breaks in this relationship, scrutinize deviations from the UIP, and employ different estimation methods and models augmented with various risk measures. Moreover, we offer several extensions to the common UIP testing that account for foreign-exchange interventions, the implied volatility of exchange rates, and the limited availability of data on direct measures of market expectations. The study shows that the choice of the reference currency matters for the outcome of the interest parity tests in the CEE economies. In particular, we demonstrate that inconsistencies between the results of the UIP tests vis-à-vis the euro and the US dollar that appear in CEE economies may be accounted for by the movements of the euro-dollar risk premium. This regularity has not been documented in previous studies. Additionally, we show that (a) the FX interventions in Czechia distorted the UIP, (b) the directly measured exchange rate expectations (granular survey data) in Poland do not seem to be informed by the UIP relationship, (c) the limited resilience of CEE economies to rare disasters may plausibly explain deviations from the UIP.

International effects of quantitative easing and foreign exchange intervention

A two-country general equilibrium model is developed to study the global consequences of quantitative easing and foreign exchange intervention. The model incorporates financial frictions such as limited commitment, differential pledgeability of assets as collateral, and a low supply of collateralizable assets. Due to differential asset pledgeability, financial intermediaries acquire different asset portfolios particular to their home country. Quantitative easing can reduce long-term nominal interest rates, mitigate financial frictions globally, and depreciate the currency of the country that supplies more pledgeable assets. The international effects of foreign exchange intervention depend on the implementing country. If implemented by the country that supplies more pledgeable assets, such intervention can ease financial frictions and enhance welfare globally.
